Materials Data on Gd2Mo2O7 by Materials Project

Gd2Mo2O7 crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. Gd3+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are two shorter (2.28 Å) and six longer (2.53 Å) Gd–O bond lengths. Mo4+ is bonded to six equivalent O2- atoms to form corner-sharing MoO6 octahedra. The corner-sharing octahedral tilt angles are 52°. All Mo–O bond lengths are 2.07 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to two equivalent Gd3+ and two equivalent Mo4+ atoms to form a mixture of distorted edge and corner-sharing OGd2Mo2 tetrahedra. In the second O2- site, O2- is bonded to four equivalent Gd3+ atoms to form a mixture of edge and corner-sharing OGd4 tetrahedra.

Materials Data on GdMoO5 by Materials Project

GdMoO5 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Gd is bonded in a 8-coordinate geometry to eight O atoms. There are a spread of Gd–O bond distances ranging from 2.29–2.51 Å. Mo is bonded in a distorted tetrahedral geometry to five O atoms. There are a spread of Mo–O bond distances ranging from 1.77–2.47 Å. There are five inequivalent O sites. In the first O site, O is bonded in a 3-coordinate geometry to two equivalent Gd and one Mo atom. In the second O site, O is bonded in a distorted trigonal planar geometry to two equivalent Gd and one Mo atom. In the third O site, O is bonded in a distorted trigonal planar geometry to two equivalent Gd and one Mo atom. In the fourth O site, O is bonded in a distorted linear geometry to one Gd and one Mo atom. In the fifth O site, O is bonded in a bent 150 degrees geometry to one Gd and one Mo atom.
